The enrgy died down, and the Doctor layed down on the floor.
He looked basically the same, but something was off. Were those... wings?
"Wuzzuh..." Said the Doctor sleepily.
He tickled himself with his wing by accident, and nearly didn't notice it.
He suddenly looked surprised at the new limbs.
"I'm... I'm a pegaus! This is BRILLIANT! Haha! I haven't been a pegasus in forever! Yesyesyesyes!!"
He said, flying around happily.
He then suddenly landed.
"...What was I doing?"
He looked at his wings.
"I'm... I'm a pegasus! When did this happen?! Oh, brilliant!!"
He once again started flying around happily.
